Patent GB-2106569-A (GB)
Title: Measuring while drilling tool
Inventor: CLAYCOMB JACKSON REYNOLDS
IPC: E21B47/18
Filed: 1982-11-08
Abstract: A measuring while drilling tool includes a closed circuit hydraulic system which is energised by variations in mud pressure and serves to modulate mud back pressure to provide surface signals indicative of well parameters. The hydraulic system includes a low pressure reservoir (215) from which five transducers are charged with fluid via a fill valve (147). The volume of fluid needed to charge each transducer is dependent on the value of the parameter detected by each transducer. Each transducer is provided with a detent valve, the detent valves being connected to a common manifold (150) and being operated in sequence by an enlargement (127) on the rod (126) of a hydraulic ram (124). When a particular detent valve is opened by the enlargement (127) the fluid contained in the associated transducer is dumped into the common manifold (150) and controls a hydraulic ram via lines (185, 200) whereby the flow area of a mud flow orifice is restricted for a period of time proportional to the volume of fluid in the particular transducer. Parameters detected may include tool inclination and magnetic heading. <IMAGE>

Title: Recovering hydrocarbon from shale oil rock
Inventor: SWANSON DR ROLLAN
IPC: C10G29/10
Filed: 1983-02-01
Abstract: Shale oil rock is reacted with a reagent, comprising an alkali metal hydrosulphide, sulphide, polysulphide or a mixture of hydrate of one or more of these, in the presence of water or steam and the hydrocarbon vapours together with spent disintegrated shale oil rock gangue are removed from the unreacted coarser particles of the shale oil rock. The shale oil rock is disintegrated into fine particles of spent shale as it is reacted at 11. The fine spent shale is removed together with the hydrocarbon vapours via a riser 12, the length and diameter of which ensure return of unreacted coarser particles to the reactor for subsequent reaction. After separation of the spent dust in cyclones 13 and 13' the hydrocarbon gases and oil vapours can be further reacted with the reagent at 17. <IMAGE>

Title: Anti-theft device
Inventor: BATEY GEORGE
IPC: B60R25/042
Filed: 1983-07-30
Abstract: A combination switch has a keyboard for entering a series of items of information for setting of the "combination". The items are received and stored in a micro-chip memory circuit. A control switch, provided for inclusion in any external electrical circuit to be controlled, is connected to the memory circuit. The memory circuit and the control switch can be put into a "setting" mode for initial insertion of a desired combination, and into an "operational" mode. Once a series of items has been entered into the memory, each subsequent entry of that series of items, and only that particular series, by use of the keyboard will cause the control switch to change its state. The combination switch may be incorporated in, for example, a fuel feed line or in a hydraulic braking system of a motor vehicle. <IMAGE>

Title: Circuit arrangement for a stroboscope
Inventor: MENSE LUDGER
IPC: G01P3/40
Filed: 1984-12-27
Abstract: A storage capacitor 4 is charged from the mains supply into a transformer 1, or voltage multiplier and a rectifier 2, a flash capacitor 7 is connected to the capacitor 4 via a emitting resistor 5 and a GTO thyristor 6, and the capacitor 7 is connected via an SRC (Symmetrically blocking) thyristor 8 to a flash tube 9 which is fired by a Testa transformer 10. The arrangement eliminates the dependence of the flash frequency and the flash energy on the de-ionising time of the gas discharge flash tubes employed. Control circuit 11 turns off the GTO thrysistor 6 when the flash capacitor 7 is fully charged. Resistor 5 is chosen so that the GTO thyristor 6 has a substantially smaller loading than the thyristor 8. At higher flash frequency and with ionised flash tubes, discharge of the flash capacitor 7 through the flash tube 9 may be controlled solely by the thyristor 8. The arrangement may be used for observations in flow technology, such as bubble formation in cloudy liquids. Flash frequencies of 5 KHz to 10 KHz may be achieved. <IMAGE>

Title: Providing positional information
Inventor: WHITNEY MICHAEL FRANCIS
IPC: G01S1/56
Filed: 1985-10-04
Abstract: In a method and apparatus for providing positional information to a radiation receiver, particularly relating to a Microwave Landing System of the Time Reference Scanning Beam kind, a beam of radiation is first swept over a range of angles in one sense (TO sweep) by one (U/R) of a pair of spaced apart scannable radiators (U/R, U/L) and then in the opposite sense (FRO sweep) by the other radiator (U/L). The interval between reception of the TO and FRO sweeps indicates the angular position of the receiver with respect to the mid-point of the line joining the radiators (U/R, U/L) and to a reference plane passing through that point, with an error that in practice is mostly very small and in particular is zero in the reference plane. The radiators (U/R, U/L) may be situated close together, suitably on the centre-line (RCL) of a runway (RY), to provide duplication in the event of failure of one radiator, or may be substantially separated, suitably symmetically about the runway centre-line (RCL), for situations in which it is undesirable or impracticable to use a conventional single scanning radiator on the runway centre-line (RCL) beyond the stop end (SE) of the runway (RY). <IMAGE>
